Magnetovision [magnetic field scanning system]

The experimental analysis of magnetic fields by scanning methods can effectively support and verify modern numerical methods. The scanning methods are especially suitable for testing the material structure and as a method for material evaluation. By applying the appropriate imaging techniques it is possible to reconstruct the magnetic field strength in an arbitrary plane. In the Magnetovision system, the specific area of a material is magnetized using a C-yoke. A line of miniature thin-film magnetoresistive sensors measures the magnetic field strength above the magnetized sample. Graphical results of the magnetic field strength scanned around steel samples are presented, showing that Magnetovision could be an effective system for nondestructive materials testing.
